' A licati filed November 28, 1904. Serial No. 234,548.

To aZZ whom it may concern.-

Be it known that I, FREDERICK WILLIAM J ACKSON, a citizen of the UnitedStates, residing at Needles, in the county of San Bernardino and Stateof California, have invented a newthree-inch opening at the end, and aregener-- ally made of medium-heavy galvanized iron.

Now in these funnels in general use the sand frequently goes all in alump, and when the exhaust from the engine is light a large part of thesand falls down in front of the oilburner, which are generally set verylow, and this sand immediately forms into heavy carbon.

It is the object of my invention to overcome these objections; and tothese ends it consists in feeding and mixing atmospheric air with thesand as it is drawn from the funnel.

It consists, further, in locating a partition within the funnel toprevent a too rapid flow of the sand.

It consists, further, in certain peculiar fea-' tures of construction,operation, and Combination of parts, as will be hereinafter fully de-'scribed, and pointed out in the claims, reference being had to theaccompanying drawings, in which- V Fig. 1 is a vertical section of alocomotive-boiler, showing my improvement as'in use. Fig. 2 is aperspective view of the device removed from the boiler fire-box. Fig. 3is a central vertical section of the same. Fig. 4-. is a perspectiveview of the partitionplate removed from the funnel. Fig. 5 shows theshape of the blank from which the partition is formed. Fig. 6 is avertical section on line 6 6 of Fig. 3.

of the shape shown in Fig. 5. pressed to the shape shown in Fig. 4 and Arepresents a funnel embodying my improvement and consists of thevertical portion A and the horizontal portion A and is made ofgalvanized iron.

B represents a partition, also made of galvanized .iron, it beingoriginally made fiat and It is then placed within the funnel proper, A,and secured thereto by means of rivets passed through the flanges B. Thelower portion of this partition, it will be noticed, is rounded to fitwithin the elbow connecting the horizontal portion A with the funnel andhas the notch B as shown in Fig. 4. The lower portion of this partition,however, does not fit closely within the part A of'the funnel, aspace'being left on each side and at the bottom between said partitionand the funnel.

'A very important feature of my invention is to admit atmospheric airand sand at the same time.

My improved device is inserted through the center of the fire-door of aboiler-furnace, and the funnel which is divided into two compartments orchambers O and D by the partition B has the compartmentD filled withsand. The sand may be packed down solid, either dry or wet sand. beingused. If wet sand is used, it may be necessary to slightly jar or shakethe funnel to get the sand running; but this willnot be necessary whendry sand is used. The compartment or chamber O is for the admission ofatmospheric air to the sand where the sand passes under the partitionand through the notch B in the lower end of said partition B and atwhich point the sand and account of the even flow of the sand in mydevice all of the flues get an even quantity of the said blast, and theoperation of the device is not dependent upon the skill of the fireman.

It will thus be seen that I provide a simple, cheap, and efiicientdevice of the character described and which can use either wet or drysand with facility.

By the use of my device the life and usefulness of the tubes andfire-box will be greatly prolonged.

By having the bottom partition set a short distance above the bottom ofthe elbow the flow of the sand will be regulated at all times, and thenotch or opening B is to permit small rocks to pass through and not clogup the space at the bottom.

When the device is not in use, it is to be taken from the opening in thefire-door and put in any suitable place, as if left in the firedoor thehorizontal portion would soon become burned ofl.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is v 1. A cleaner for boiler-fines consistingof a funnel having a horizontally disposed discharge-opening at itslower end, and a vertical partition within said funnel dividing the sameinto two chambers, said chambers communicating with each other adjacentto the dischargeopening ofthe funnel.

2. Acleaner for boiler-fines consisting of a funnel adapted to belocated exteriorly of the front wall of the fire-box, a discharge-tubeleading from the funnel into the fire-box, and a partition within saidfunnel dividing it into two chambers, one of which is for sand and theother for atmospheric air, said partition having an opening at its lowerend establishing communication between the sand and air chambers,whereby the sand and air will be mixed and discharged asa spray to theflues by a draft within the fire-box of the boiler.

3. A cleaner for boiler-fines consisting of a funnel located exteriorlyof the front wall of the fire-box, a discharge-tube leading from-thefunnel and adapted to pass through the firedoor and into the fire-box, apartition within the funnel dividing the funnel into two chambers one ofwhich being for sand and the other for atmospheric air, said partitionhaving a passage at its lower end connecting the two chambers and saidpartition being inclined rearwardlya portion of its length and then eX-tending downwardly vertically to the discharge-tube.

4. A cleaner for boiler-flues consisting of an upright funnel andhorizontal discharge communicating with the funnel at its lower end, anda partition secured within the funnel dividing the same into twochambers, one for sand and the other for atmospheric air, said partitionhaving an opening at its lower end establishing communication betweenthe aforesaid chambers.

55. A cleaner for boiler-fines consisting of an upright funnel, ahorizontal discharge-tube communicating with the funnel at its lowerend, and a partition secured within the funnel dividing it into twochambers, said partition having a rearward slant and curvedlongitudinally, and provided with an opening at its lower endestablishing communication between the aforesaid chambers.

6; A cleaner for boiler-fines consisting of a funnel adaped to belocated exteriorly of the front wall of the fire-box, a discharge-tubeleading from the funnel into the fire-box, and a partition within thefunnel dividing it into two compartments, said partition extendingdownwardly into the funnel and having its lower end reduced intransverse area, whereby a space will be left between the lower end ofthe partition and the side walls of the discharge-tube.

7. A cleaner-for boiler-fines consisting of an upright funnel, and adischarge-tube extending at an angle therefrom, and a partition locatedwithin the funnel and dividing the same into two chambers, saidpartition having a notch at its lower end and set off from the sidewalls of the funnel whereby a space will be formed around the lower endof the partition to permit free passage of sand to the disl/Vitnesses:
